摘要： A multimode queuing system (600) for DiffSery routers is provided. The multimode buffering and scheduling system that can be adjusted to show either "pure" Assured Forwarding/Expedited Forwarding (AF/EF) behavior, "pure" DiffServ Urgency Importance (DSUI) behavior, or a combination of the AF/EF behavior and the DSUI behavior. An operation point parameter may be set to select the desired behavior. DiffServ products utilizing the combination of the behaviors are flexible and more configurable as compared to only AF/EF products. The multimode queuing system deployment is simple and is a low cost modification to DiffServ routers. The same hardware and/or software implementation can support both mechanisms with very small additional cost and effort. Also the management of the system is simplified. For example, there is no need for several parallel queuing systems.A multimode queuing system (600) for DiffSery routers is provided.

摘要： A data communication node capable of operating under, for example, TCP protocol in two or three of the following modes: a normal mode in which it does not affect communications; an early acknowledgement mode in which it transmits early acknowledgement messages for datagrams that have not yet reached the node; and a fast TCP mode in which it delays the communication of acknowledgement messages to the transmitter.

摘要： The present invention relates to a method and system for handling congestion in a packet data network, wherein at least two operating modes of congestion handling are selected based on a detected congestion level. The operating modes will then affect the applied congestion handling modes to thereby achieve a flexible and automatic network response which is based on the congestion level. Thereby applications' quality requirements and service provider's business goals can both be met in an adequate manner.

摘要： A broadband cellular network device comprises a base station controller unit (1), an asynchrouous transfer mode controller (2) adapted to control the distribution of cellular traffic consisting of asynchrouous transfer mode cells in trunking mobile communication networks based on ATM technology, and an asynchrouous transfer mode switching means (3) controlled by said asynchrouous transfer mode controller (2). The base station controller unit (1), the asynchrouous transfer mode controller (2) and the asynchrouous transfer mode switching means (3) form an ATM based base station controller (BSC) capable of performing ATM switching and adapted to replace PCM based base station controllers in base station subsystems (BSS) of asynchrouous transfer mode based cellular networks.

摘要： The present invention relates to a method and network node for controlling packet flow in a buffer means ( 13; 14 ) of a network node of a data network, wherein a nominal capacity is assigned to each data flow, and an additional or free capacity is shifted from a first flow portion to a second flow portion when a new data packet of said second flow portion has been received and said nominal capacity has been exceeded. The nominal capacity may be an upper buffer memory limit used for controlling queuing of data packets in a buffer memory ( 13 ) of said buffer means, wherein the memory space of the buffer memory ( 13 ) is shared between a plurality of channels allocated to respective packet data connections. Then, the free capacity corresponds to a memory space shifted from a first channel to a second channel, when a new data packet of the second channel has been received and not enough memory space is available for the second channel. Thus, a dynamic buffer-sharing mechanism is provided which reduces the number of packet drops in the buffer memory ( 13 ) during congestion and improves network throughput. Alternatively, the nominal capacity may be a nominal flow rate at which data flow traffic is guaranteed in a QoS scheduling algorithm. Then, a residual rate corresponding to the difference between the nominal flow rate and an instantaneous traffic is shifted between flow portions of a buffer means controlled by the scheduling algorithm to maximize total system throughput.
